6 Planned research Starting Point Rising complexity, interdisciplinary, multi nationality in today's research questions involve researchers from several countries, disciplines e.g. PrimeLife involves researchers from areas like Economics, Social Science, Computer Science, Law, and others as well as from countries like Sweden, Switzerland, Germany and so forth to conduct integral research. The increasing amount of data to be stored and processed not only in quantum physics but more or less every scientific discipline introduces an increasing need for resource sharing. Cost saving initiatives, global distribution of experts and events like the breakout of the volcano Eyjafjallajökull create the need for a Plan B to overcome travel restrictions. International research promotions (e.g. EU-Funding Plans) by nature involve researchers from several countries and therefore introduce the need for collaborative work. 6

7 Complexity (Research Questions, Organizational,...) Costs pressure (Budget cuts, Funding reductions,...) Scarce Resources (Experts, Equipment, Time,...) Reusability (Raw Data, Results,...) Networking (Junior Researchers, Project Partners,...)... Planned research Starting Point These issues aren t new but they reach levels where they put research projects at risk or at least reduce their effectiveness as well as their efficiency. 7

8 Planned research Starting Point Today s concept to deal with the named issues mostly employ technologies like: (unsynchronised, offline communication) Web 1.0 (Webmaster/Author managed content) Remote Processing (rsh, rexec, rlogin,...) Ping Ponging of Documents Face to Face Meetings Mailboxes, Newsgroups,... These technologies still work out as one can easily see with the amount of successful research projects completed. But are they as efficient and effective as they could be? 8

9 Planned research Assumptions Assumption - Employment of new technologies should help better overcome the issues and (as side effect) should enable new research approaches as well. The selected Concept: Master thesis -> focusing on Shared Workspaces as described in the Paper of Hönig and Schiffman, University of Hagen (supervisor of my master thesis): Shared Workspaces: A Concept for implementing a Distributed escience- Environment in Grid- and Cloud-based Infrastructures. 9

11 Introduction to the underlying Concepts Cloud Computing Data Cloud is the underlying Infrastructure for Shared Workspaces. Data Cloud = utility alike availability of storage 11

12 escience electronic / enhanced Science Introduction to the underlying Concepts escience e-science is about global collaboration in key areas of science... (using very large data collections, terra scale computing resources and high performance visualisation)..., and the next generation of infrastructure... (Grid-Computing)...that will enable it. John Taylor, Director General of Research Councils Office of Science and Technology escience = employment of Grid-/Cloud-based infrastructure and technical enablers to e scientific research 12

13 Introduction to the underlying Concepts Shared Workspace Shared Workspaces (SWS) use Grid-/Cloud-based technologies to enable escience Directory Directory is used for locating SWS, to store data index (tags), profiling data,... SWS provided by User A and accessed by User B, MW seamlessly integrates SWS to File systems 13

15 Two Steps: Work Planned Steps to go 1. Master thesis Focus: Evaluation of a given selection of Open-Source Social Networking Software (SNS) for the integration in SWS-Concept 2. PhD Research based on the lessons learned from Step 1 further Research 15

16 Step 1 Master thesis Work Planned Master thesis Build a Lab Infrastructure (collect experience with Private Cloud) build out of desktop systems based on virtualized Linux Systems Analyse the Lab Infrastructure with Focus on the Usefulness for Shared Workspaces collect experiences with cloud solutions Implement Concept of SWS to Lab Infrastructure implementation of all necessary SWS components (middle ware, directory...) Discover requirements for enhancement of SWS by SNS 16

17 Step 1 Master thesis Work Planned Master thesis Analyse the given SNS s with regards to how Directory data could be used for Networking, Access Control, SWS Search,... Unmodified SNS s will be analysed on their capabilities to support SWS requirements Find a first set of necessary information to be held in the Directory -> Expert Interviews, literature study, own experience Develop a first version of the directory and test it against given SNS s 17

18 Step 1 Master thesis Benchmark/Evaluation of the given SNS s in SWS context Work Planned Master thesis Installation effort, Technical requirements, Feature set, Access control, Profiling capabilities, API s... Conclusions, Suggestions for a first version of the Directory and the usage of SNS s in the Concept of Shared Workspaces what is needed to make SWS a fully useful, secure, reputable Concept discovered issues, possible concept modifications ideas for further research and development -> some ideas already exist 18

19 Step 1 Possible Future Research as known by now HCI - Usability Implementation of distributed Directory Community driven Reputation mechanisms Secure Documents Change control of data Security and Privacy issues... Not covered by my work planed, but important questions. Work Planned Post Master thesis 19

20 Work Planned PhD Research Step 2 Possible PhD Research focus on Future Research from Step 1 Security, Privacy (Individual/Organizational) aspects of Cloud Computing Organizational aspects of the employment of Cloud Computing Governance...? Ideas for future PhD research derived from the described Master thesis. 20

22 Questions for Discussion Master thesis related Questions and Discussion What are the major issues in Interdisciplinary Research with regards to cooperative work? How are they addressed today? What are potential Security issues in a SWS scenario? What feature should a Science/Research focused SNS to be implemented in SWS provide? Is there any applicable SNS Benchmark known to you? PhD Research related My Focus What would a promising research focus in Cloud Computing be? Security, Privacy, Governance, ITIL for the Cloud, Organizational aspects Cloud of Clouds -> the one and only Cloud 22
